Abstract
A process is disclosed for the preparation of perfluoroalkanols by reacting an ester of a perfluorinated acid in the liquid phase with hydrogen under a pressure of between about 1 and 300 bars in the presence of a catalyst based on at least one metal selected from nickel, cobalt, copper and the metals of the platinum group. The perfluoroalkanols are employed as synthesis intermediates in the pharmaceutical and plant-protection industries.
